MECHANICAL MOVEMENT.

To all whom it may concern:

Be it known that I, JEREMIAH D. WINDSOR, a citizen of the United States,residing at Nokomis, in the county of Montgomery and State of Illinois,have invented a new and useful Mechanical Movement, of which thefollowing is a specification.

This invention relates to mechanical movements and more particularly tomeans whereby the pounder of a washing machine can be given a combinedrotary and reciprocatory movement by the rotation of a main or driveshaft.

Another object is to provide a simple form of mechanism whereby thismovement of the pounder may be obtained, said mechanism being formed offew parts and therefore durable and easy to operate.

Another object is to provide mechanism of this type which can be easilycleaned and all parts of which are readily accessible for the urpose ofmaking repairs, etc;

ith these and other objects in view the invention consists of certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claim.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings, Figure 1 is a front elevation of the operatingmechanism of the washing machine, only a portion of the easing of saidmachine being shown. Fig. 2 is a detail View of the guide post or standard of the mechanism. Fig. 3 is a section on line AB Fig. 1. Fig. 4: isa section on line C-D Fig. 1. Fig. '5 is a section on line E-F, Fig. 1.

Referring to the figures by characters of reference 1 designates aportion of the casing of a washing machine and secured upon th1s casingis a base plate 2 having a tubular standard 3 thereon and integraltherewith, this standard being provided with an elongated slot textending spirally around the standard for about one quarter of thecircumference thereof.

A rod 5 is mounted for sliding and rotary movement within the standard 3and is provided at its lower end with a suitable pounder 6 while itsupper end has an enlargement or head 7 through which extends a slot 8,the said slot being flared from its center to its outer ends as shownparticularly in Fig. 3, the walls at the sides of the slot beingpreferably disposed at right an- Specification of Letters Patent.

gles to eachother and there being sufiicient space between opposed wallsto receive a pin 9 which extends perpendicularly from the upper end of apitman 10. This pitman is mounted on a wrist, pin 11 extending from acrank 12, the said crank being secured to and actuated by a shaft 13.This shaft is journaled in standards 14 secured on the casing 1 and isdesigned to be driven many preferred manner as by means of a wheel 15.

A screw 16 engages the rod 5 and extends radially therefrom and throughthe slot 4: in standard 3, this screw constituting a bearing for a guideroller 17 the diameter of which is slightly less than the width of theslot, there being a head 18 upon the screw for holding the rolleragainst displacement.

By providingmechanism such as herein described it will be seen that whenshaft 13 is rotated by means of the wheel 15 the crank 12 will transmitmotion through the I pitman 10 to the pin 9 and the rod 5 will thus bereciprocated within the tubular standard 3,.causing the pounder 6 tomove upward and downward therewith. During this movement of the rod 5the roller 17 will travel within the spiral slot 4 and cause the rod tomake a one-quarter rotation during the upward movement thereof or duringits downward movement it will make a one-quarter rotation in theopposite direction. The action of the pounder 6 will thus be such as toquickly clean the fabrics engagedthereby because of the rubbing andpressing action exerted thereagainst.

As shown particularly in Fig. 5, apitman 19, may be mounted on the wristpin 11 between pitman 10 and crank 12, this pitman 19 extendinglaterally and being pivotally connected to a lever 20 which is fulcrumedupon one side of the tub 1. By providing a lever such as shown anddescribed the machine can be actuated either by means of the wheel 15 orby the lever 20, according to the wishes of the operator. When the leveris used the wheel 15 operates as a fly wheel.

By mounting the roller 17 upon a screw extending radially from the rod5, the said roller can be readily reached for the purpose of replacingor adjusting it, and moreover, the roller lies close to the rod and thetransverse strain upon the screw 5 is thus reduced to the minimum. Theconnection between the pitman and the rod is advantageous because itdispenses with the use of a swiveled over the pin 19 can be screwthreaded so as to detachably engage the pitman, and, therefore, the samecan be readily removed for the purpose of detaching the pitman from therod.

It is of course to be understood that various changes may be made in theconstruction and arrangement of the parts without departing from thespirit or sacrificing any of the advantages of the invention.

lVhat is claimed is In a washing machine, a stationary tubular standardhaving a spiral slot, said slot extending partly around the standard, a

rod mounted to reciprocate and rotate With- 1 roller journaled on saidelement and mounted to travel within the slot, a head upon the rodhaving a diametrical slot therein, the said slot increasing in widthfrom its center to its ends, a pitman, a pin detachably engaging thepitman and extending through the slot, a crank for actuating the pitman,an oscillatory actuating lever, a connection between the crank andlever, and a wheel revoluble With the crank.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
